Channel Breakout, Power Breakout Boards


Power Breakout Board, comes with mosfet polarity protection. No onboard regulator, intended for projects that have a dedicated high wattage supply already (no puny 7805).



Channel breakout board, supports up to 16 ports (Supports servos too), and powered by the connector on the right hand side, therefore you can power them off their own dedicated supply.

30 Amp Dual motor Driver, Krumtroller Order requests

The Krumtroller has been generating alot of interests lately, and Ive been working on a 2nd revision of the board. It's cheaper than the other boards, because I'm not looking for profit first, I'm far more interested in helping out LMR'ers and further their projects. Therefore, I am offering the Dual Motor Driver, featuring Current sensing, PWM control and bidirectional motor control for Just 50 dollars. This board can handle 30 amps and Fits under 70mm square, and has standardized mounting holes so you can mount any LGA775 compatable cooler for the board.

Supersonic Golf Ball

Well, good news everybody! I have managed to get a team of people together that are willing to pool resources together for construction of a high energy supersonic Golf Ball cannon, complete with remote electrical control and operation. The Cannon will feature complete autonomous reloading of the barrel. I will have to create large quantites of gun cotton, otherwise known as nitrocellulose. Nitrocellulose has been used as a propellant and explosive for many years.

Maze Solving Robot Progress


Progress on my Maze Solver:
Mainboard: Schematic Done, Board Layout Done
Sensor Board: Schematic Done, Board Layout Done
Programming: Haven't started
CAD: Done!

Finished the sensor board, took some screenshots of it in cad, added to attachments.

I will package all necessary files in a zip so anybody can build this robot. I just recieved the PCB materials today, so hopefully tomorrow (Jan 19) I can etch the boards and start assembling the robot.

Coil Gun Rifle

I have been making soem good progress on the Coil Gun Rifle:



Larger images in attachments.


Arc Point Art

Well, I had some fun in the attachment. I would take a sheet of flexible circut stuff, and charge my 24Joule Capacitor bank. i would then short out the points between the plate and the wire, vaporizing the copper at the point, creating a black spot. In the attachment, I spelled KL!, mostly because I diddnt have that much to mess with :)

 I was thinking of doing LMR next :)

The BIG board!

Ok, though you would like to see what I am working on now. I am having this as a blog post  until there is something worthy of posting. It sure looks cool or what :)
